CHARLES M. ARTHUR, OF EVANSVILLE, VISOONSIN.

PAPER BOX.

SPECIFICATION forming part of Letters Patent No. 310,241, dated January6, 1885.

Applica-tion led September 15, 1884. (Model.)

To all whom t may concern.-

Be it known that I, CHARLES M. ARTHUR, of Evansville, in the county ofRock and State of Visconsin, have invented certain new and usefulImprovements in Paper Boxes; and I do hereby declare that the followingis a full, clear, and exact description thereof, reference being had tothe accompanying drawings, and to the letters of reference markedthereon, which form a part of this specification.

This invention relates to the class of collapsible or knoekdown paperboxes, and more especially to such boxes of the telescoping variety.

The several branches ofthe invention concern the form of the blank, theYform of the fold, and the attachments of the collapsed andpartly-joined box, and the completed structure.

The invention consists in the mattershereinafter fully set forth, andpointed out in the appended claims.

In the accompanying drawings, Figure l is a perspectiveview of ateleseoping form of paper box for which my improvement is moreparticularly designed. Fig. 2 shows an extended blank from which anopen-ended paper box adapted to form one half a telescoping box may beformed in accordance with my present improvement. Figs. 3, 4C, 5, and 6illustrate the blank variously folded, showing different stages in thefolding of the blank,

and in some particulars also showing dissimilar forms of folds madetherein in completing the collapsed and pasted structure from the blank.Fig. 7 is a perspective view of an open-ended box, which may form eitherthe outer or the inner of two parts of a telescoping box, such as isshown in Fig. 1, but which ,contains a certain peculiarity ofconstruction that particularly ts it to form the outer one of sai parts.Fig. 8 is a perspective interior view of onev` half of the open boxshown in Fig. 7, divided in the plane of the line :o x, and lookingtoward the side C. Fig. 9 is an interior perspective view of theopposite half of the said box, or looking toward the side A. Fig. l0 isa perspective interior view of one half of the box shown in Fig. 7,vertically divided in the plane of line y y, and looking toward the sideD. Fig. Il is an interior view of the opposite half of the box, orlooking toward the side B. Fig. 12 is a view of the same part of the boxas shown in Fig. ll, when the several parts of the box-bottom occupy therelation given them in that form of fold in the blank shown in Fig. 6.

One of the objects of this invention is to pro-V vide a form of blankfor a collapsed or collapsible paper box in which two parts which,either in the collapsed or in the finished box, are to be located atadistance from each other, are brought in line with and adjacent to eachother, so that the paste, glue, or other adhesive agent may beconveniently and rapidly applied to said parts, and in which, when themembers ofthe blank are folded upon each other to form the collapsedbox, bothpasted surfaces are brought into proper position for attachmentwith the members with which they are to be joined.

Another object of theinvention is to provide a construction in acollapsed box in which not only the lap whichjoins the sides is pastedor secured, but in which the interior lap, which connects one of thebottom iiaps to the appropriate side of the box, is also permanentlysecured, so that it fully sustains said bottom piece, and also bringsthe latter perfectly and promptly to its place in the operation offinally setting up the box.

Still another object of the invention is to provide a form of theinteriorly-projecting lapping partial side of the outer part of atelescoping box, whereby said lapping and projecting member will offerlittle obstruction to the application of the parts of the telescopingbox to each other.

. In Fig. 2, which shows the blank extended, full lines indicate throughcuts at which the adjacent parts are entirely separated, and dottedlines indicate 'scores to facilitate folding, except the dotted lines atthe margin of the member D', whi ch indicate one allowable variation inthe form of said member.

A, I3, O, and D in the blanks shown are IOO -f to said side by paste orglue.

F, F, and G are adjacent continuations of the several members, A, B, andC, respectively, intended to formy the closed end oi' the box when thelatter isset up, and called end 5 pieces7 or end flaps.77 Theceiitralend piece or flap, F, is provided with an extension, DZ,

intended to form a tuck ,to hold the said iiap in place in the completedbox in a familiar manner. Through cuts in the blank completely [Oseparate said end iiaps, E, F, and G, from each other, but all theseparts or members are separated from the side members by scores, and ascore also marks therdivision of the tuckiiap D2 from the end piece F.

I 5 D' is a lateral continuation of iiap G, reaching to or near the freeedge of the lap-piece A, and commonly narrowed to a point at its outerend, as shown. Said part D is intended to fold upon the inner sidemember, D, with 2 j its point or end d at d', Figs. 2 and 3, and to bepermanently secured at this point or end The said end piece G has ascore-line, g, which bisects the angle adjacent to the side D,to permitthe said end piece to be temporarily folded upon itself for the purposeof forming the collapsed and partiallyjoined structure. This particularscore-line forms a single feature in a former invention, set forth inLetters Patent of the United States No. 234,221, dated November 9, 1880,and is not here independently claimed. It is of course understood thatthe lap A is to be united by paste or glue to the inner face of the sideA at its edge ct. It is desirable, in

order Yto readily and economically accomplish the pasting necessary tojoin the lap-piece A with the side A and the extremity of the meniber DWith the slide D, as described, that the said extremity of the member Dand the lap- 4o piece A be arranged adjacent to each other,

as shown.

In the following description it may be understood that the paste hasbeen applied to the under surface of these parts A and D by somesuitable device or means While the blank is in its extended form, asshown in Fig. 2. After Vbeing pasted the members of the blank are foldedin their score-lines, substantially as will be next described.

lVith a view to imparting greater supporting strength to the closed endof the completed box, I prefer to turn the iiap G toward the side C, andto simultaneously fold said flap G upon itself by bending it in thescore-line g.

This operation brings the several members G and D into the positionsindicated in Fig. 3, with the pasted surface on the part D uppermost. Next, the side D maybe folded over the parts C, D', and G, bringing the6o pasted surface of the lap-piece A uppermost, in the positionindicated in Fig. 4, and also bringing the inner surface at d of theside D into contact with the pasted surface d of the part D. The side Ais then folded upon the 6 5 side B and pasted lap A', as indicated inFig. 5, a permanent union of the side with the lap being effected by theapplication of suitable pressure of the hand or otherwise. The blankbeing thus folded and joined in two places presents the collapsedstructure shown in plan in Fig. 5. Said structure is obviously capa bleof being expanded and further folded to form an open-ended box, T L, atany time, by first pressing the extreme lateral edges thereof until thesides are at right angles with each other, and then turning in the iiapE over the thusextended end piece G, and finally folding the outer flap,F, over E and thrusting its tuck DZ into the space between the members Dand D. The arrangement of the end pieces just described is shown inFigs. 8,- 9, 10, and 11.

Still greater strength may be obtained in the closed end by proceedingas follows from the stage of the folding represented in Fig. 3-that isto say, first turn the flap E against the side A, and` thensimultaneously turn the sides A and D toward each other, inserting thelap A between A and E as both are borne down upon the underlying sides Band C. Thereafter the fiap F D2 may be folded over into the positionshown in Fig. 6, if desired., giving to the collapsed structure thecompact rectangular form presented by said Fig. 6'. In finally settingup the box having the end piece E upturned, as last described, thebottom piece, G, (as before,) straightens out of itself when the sidesare brought to right angles with each other, and the flap E will need tobe pushed down upon it by the finger from the inside of the box, afterWhich the flap F and tuck DIl are disposed of as before set forth. Thearrangement of the bottom pieces will, in this case, have the relationsshown in Fig. 12.

In bringing the member D upon C, instead of folding the end piece G uponthe side member, C, as above suggested, and as shown in Fig. 3, said endpiece may be simply folded upon itself in the diagonal score g,- butinthis case the form of collapsed box shown in Fig. 6 is not obtainable.

In the use of an open-ended box formed as and from the blank describedfor the larger or outer part of 'a telescope box, such as is illustratedin Fig. l, the inclined direction of the projecting edge of the member Dfavors its passage over the upper edge of the inner half-box, and thusfacilitates putting the two telescoping parts together.

I claim as my invention- IOO IIO
